What does it feel like to leave Earth?

Imagine sitting in a futuristic cabin, enjoying the sensation of weightlessness. As you glance out the window, you don't see the sky-blue hue but the blackness of space. You are gazing at the Earth below and experiencing the void of the vast space. The dream of travelling to space, which was only for astronauts once, is now within reach of civilians who have the means to buy tickets.

Companies like as SpaceX, Blue Origin, and Virgin Galactic envision transporting ordinary folks who can buy the tickets into orbit. With the Inspiration4 mission, SpaceX launched an all-civilian crew into orbit, setting a new standard for commercial space travel. The idea was to demonstrate that becoming an astronaut is not required to experience space. The crew flew with the 'resilience' capsule, which was launched atop a Falcon 9 rocket, and orbited Earth many times during their three-day journey.

But what can you expect from a commercial voyage to space, and what do you need to have this experience? Here's a comprehensive overview of the space exploration process.

How it feels
At the beginning of the take-off, the passengers will feel intense vibrations. They will be met with a crushing sensation of G-forces pushing down on them. As the craft blasts off the Earth's surface, entering space, the window will shift from blue to infinite black in space.

After reaching space, the engines will be turned off; the passengers will be able to experience microgravity, the most highlighted experience of the flight. 

They will be able to float freely around the cabin as they wish. Looking out of the windows, the Earth can be seen as a delicate blue sphere. Depending on the flight, multiple sunrises and sunsets can be witnessed while orbiting the Earth. 

While returning, the passengers will once again feel the g-force, though in reverse this time. Re-entry is a critical phase of the flight. The plasma can be seen glowing as the spacecraft re-enters the atmosphere at high speed.

Expense
You, too, can experience space, but there are a few things you'll need. The obvious one is money, as space tourism is a luxury experience. Companies like Virgin Galactic or Blue Origin offer suborbital flight seats for $250,000 to USD 450,000. 

If someone wants to spend more time in orbit, they have to spend tens of millions of dollars on SpaceX's missions. However, prices are predicted to drop as more competitors enter the market. But for now, space exploration remains an experience for the wealthiest individuals.

Even in a commercial setting, the passengers need to be medically fit to be subjected to high G-forces during take-off and re-entry. 

Training
A series of medical exams are done to ensure the passenger is in overall good health to handle the rigours of space travel. One may also need to go through physical training to prepare for microgravity and different levels of force. 

In the training, the passengers are familiarized with the spacecraft, taught how to move and function in microgravity and understand emergency procedures. 

The psychological resilience of the passengers is also evaluated as enclosed spacecraft, and viewing Earth from orbit can be stressful. All passengers receive simulations, virtual reality, and counseling sessions to assist them cope with the unique psychological components.

While commercial space trips remain elite and expensive, they are only the beginning of human exploration. 

Space flight will become more affordable as technology advances and expenses fall. The future of commercial space travel promises many more possibilities, including journeys to the Moon and possibly Mars.
